CEO-Bench: Can Agents Play the Long Game?

arXiv:2606.18543v1 Announce Type: new Abstract: Language model agents are becoming proficient executors at isolated, short-horizon tasks such as software engineering and customer service. Yet real-world challenges require a combination of sophisticated skills that remain largely untested in agents: (1) navigating long horizons amid uncertainty; (2) acquiring information in noisy environments; (3) adapting to a changing world; (4) orchestrating multiple moving parts toward a coherent goal. We introduce CEO-Bench, which evaluates these capabilities together by simulating a representative real-wo

Why this matters
Why now

The proliferation of language models has enabled researchers to push the boundaries of agentic capabilities, prompting a need for more sophisticated evaluation benchmarks that reflect real-world problem complexity.

Why it’s important

Measuring the long-term, adaptive, and orchestration capabilities of AI agents is crucial for understanding their true potential and limitations, especially for complex enterprise and societal applications.

What changes

The introduction of CEO-Bench provides a new, more rigorous standard for evaluating AI agent performance beyond isolated short-horizon tasks, thereby accelerating research towards more capable and robust autonomous systems.

Winners
  • · AI Agent developers
  • · Enterprises adopting AI for complex workflows
  • · Open-source AI research
Losers
  • · AI models only optimized for short-term tasks
  • · Companies with simplistic approaches to AI agent integration
Second-order effects
Direct

CEO-Bench will drive significant advancements in AI agent architecture and training methodologies.

Second

More capable AI agents will begin automating multi-stage, complex white-collar tasks, impacting professional service sectors.

Third

The demonstrated ability of agents to navigate long horizons and adapt to changing conditions could lead to entirely new organizational structures and business models.
